- the point 100 of the central zone is fixed directly on the support element 56.
- the flexible constitution of the second movable part also allows the two contacts 36 and 41 to be closed simultaneously.
- the contacts can be opened or closed independently, in particular by electromagnetic controls.
- a second movable part 33 is made of a material comprising a part with predominantly permanent magnetization, for example a longitudinal magnet 103 comprising contact pads at each end.
- the electrical contact zones can be produced by depositing suitable metal or by adding thin contact pads.
- the magnets can have various shapes and be fixed on fixed or mobile parts of the magnetic elements.
- the magnetic or magnetizable elements can also be covered with material depending on the intensity of the current which must pass through the contacts. The current can reach several amperes in a small volume.
- the electrical devices which may include a switching device according to the invention can be very diverse, for example, low or high power switches, circuit breakers, auxiliary contacts, contacts controlled by mechanisms or manually.
